A case of dermal nerve sheath myxoma on the left palm of 26-year-old Japanese man is presented. We examined this tumor by light and electron microscopies. On light microscopic examination, this tumor was characterized by a multilobulated myxoid tumor composed of stellate cells in an abundant mucous matrix. This histological feature resembled previously reported cases of dermal nerve sheath myxoma. On electron microscopic examination, the findings of these tumor cells were similar to those of the perineurial cells. These microscopical examinations have provided evidence for an origin from perineurial cells rather than Schwann cells.
本文报告一例26岁日本男性左手掌皮肤神经鞘黏液瘤病例。我们通过光镜和电镜对该肿瘤进行了检查。光镜检查显示，该肿瘤具有多叶状黏液瘤的特征，由星状细胞组成，存在于丰富的黏液基质中。这种组织学特征与先前报道的皮肤神经鞘黏液瘤病例相似。电镜检查发现，这些肿瘤细胞的表现与神经束膜细胞相似。这些显微镜检查结果为该肿瘤起源于神经束膜细胞而非施万细胞提供了证据。
